Abstract

For very many years glial cells were considered mere “roadies” to their more glamorous and high-octane “rock star” counterparts – the neurones. Thus, glial cells were expected to perform the functions that roadies would on a rock tour – provide transport, supply nutrients, take away waste, procure and provide chemical substances, solicit or repel groupies (accessory entities required at appropriate times), provide physical support and generally hold everything together.
